答案　A

　　.根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

　　I live in Japan, where electronic items are a way of life, so

　　it is no surprise that many students carry these little electronic dictionaries. E－dictionaries may be light and compact(简洁的) more so than any paper dictionary.__1__It depends on which one you buy. To me, these are pretty much the limits to their advantages.

　　I think e­dictionaries should be limited in their use in classrooms. __2__

　　E­dictionaries are much more expensive. In Japan, they cost as little as 10,000 yen (US $100) much as 40,000 yen, depending on how many functions you want (or think you want) and depending on how fashionable you are. My trusty Random House paper dictionary is copyrighted at 1995, cost me a mere US $12.95 plus tax.

　　E­dictionaries are more fragile(易碎的). Drop your paper dictionary. Go ahead. Hold it above your head and drop it. __3__

　　E­dictionaries need batteries.

　　Batteries are temperature sensitive. Batteries cost money, too.

　　E­dictionaries have keypads. Typing in the spelling of a word is harder and more time consuming than looking through pages and using the index at the top of each page.

　　__4__Such little devices beep(嘟嘟声) when you press the buttons, but it is very disturbing to some people in a classroom situation or library.
